TO ALL WHOM IT MAY CONCERN:

Be it known thatI, L. F. SMITH, ot' Philadelphia, in the county ofPhiladelphia, and in the State of Pennsylvania, have invented certainnew and useful Improvements in Steam-Blowers; ,and do hereby' declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon. I I

In the annexed drawings, making part of this specification, A representsa large pipe, made of anysuitable diameter, and provided with a flaringmouth, as seen from a to a' B B represent two partitions, which areplaced in the mefuth of the pipe, at equal distances on each side of itscentre, but leaving air-passages, asl

seen bythe arrows 1 and 2, between them and the sides of the pipe.'Fitted in snugly between these partitions, is a metallic box, G'. Thisbox has rmly secured into its outer end a steam-pipe, D D. The inner endof this pipe is forked, and each fork is provided with a series of smalloriiices, e e e and e e' e', for the escape of steam. Placed centrallywithin the pipe A is a diamond-shaped spreader, E. One angle of thisspreader projects in between the divisions or partitions B B, .and alsobetween'the forked ends of the pipe D.

The object of this invention is to crcate,'and continue, as long` asdesirable, a currentor draught of air by means of steam. Steam isadmitted through pipe D, and, rushing through the orifices ee', strikethe sides of the Ipipe A in the direction of the dotted linesrepresented at a: x.- The spreaderE causes this deiiection of the vsteam, and the pipe A, being thus instantly filled with st eain, has theair displaced within it. The external air;

rushes in to supply that displaced, andpasses by the partitions B B, inthe direction of the arrows 1 and 2, and after passingg` the lines :u:z: is forced onward by the steam from the orifices e e. As long as acurrent ot' steam is allowed through the orifices e e', so long will acurrent of air be forced through the pipe A. The air thnsforeed may heused for Ventilating purposes, or for supplying oxygen to the fire of afurnace.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The spreader E,.as constructed and arranged within the pipe A, withits partitions B B, in the manner and for the purposes set forth.

2. In combination with the vspreader E in the pipe A, with itspartitions, the solid pipo or casting D, having orifices e e andscrew-thread, all constructed and operating as specified.

In testimony that I claim the foregoing, I have hereunto set my hand,this 28th day of September, 1867.

L. F. SMITH.
